trun.p: Truncated Cumulative Density Function of a gamlss.family...

Description

Creates a truncated cumulative density function version from a current GAMLSS family distribution.

For continuous distributions left truncation at 3 means that the random variable can take the value 3.
For discrete distributions left truncation at 3 means that the random variable can take values from 4 onwards.
This is the same for right truncation. Truncation at 15 for a discrete variable means that
15 and greater values are not allowed but for continuous variable it mean values greater that 15 are not allowed
(so 15 is a possible value).

Usage

Arguments

par

a vector with one (for left or right truncation) or two elements for both

family

a gamlss.family object, which is used to define the distribution and the link functions of the various parameters.
The distribution families supported by gamlss() can be found in gamlss.family.
Functions such as BI() (binomial) produce a family object.

type

whether left, right or in both sides truncation is required, (left is the default)
